Service Description: Low-Res boundaries of the native regional corporations created by the Alaska Native Claims Settlement Act (ANCSA). As of early 2025 these are still very old legacy boundaries digitized off of small scale maps - and are only suitable at scales of 1:500,000 or smaller. Review indicates in some cases that they should follow Township, Range, or Drainage boundaries but set has not been touched likely since the 90's. Also note that of course of the entire polygons portrayed the actual acreage that actually was conveyed or is yet to be conveyed to ANCSA Corporations and Village Corporations is a very small fraction of the total acreage.

Provided as a frame of reference. Master set of actual status of conveyances are tracked by BLM Alaska - see group page https://www.blm.gov/programs/lands-and-realty/regional-information/alaska/land-transfer
